FLEXIBIiE-HOSE PROTECTOR.

Patented-May 20, 1913.

To all whom it may concern:

Be it known that I, JOSEPH D. HAnms, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Flexible-Hose Protectors, of which the following is a specificat-ion.

This invention'relates to a hose protecting device, more particularly for the flexible hose which is employed between railway Years to connect up train pipe lines.

In fitting up flexible hose, a nipple adapted to be connected to the train pipe, is sllpped mto one endof the hose and clamped and a coupling half section is similarly applied to the otherend. The nipple and coupling ends which are forced into the flexible hose sometimes have burs or rough projections which are liable tocut. and damage the inner tube of the flexible hose bot-h in assembling and in service when the hose is stretched by the cars pullin apart. This is of course very objectionable and it is highly desirable to avoid such damage.

The main object of my invention is to obviate this difliculty and for this purpose the invention comprises a protecting metallic cap adapted to surround the nipple end and thereby prevent contact between the inner tube of the hose and the nipple.

In the accompanying drawing; Figure 1 is a central sectional view of a nipple connected to a flexible hosesection," illustrating one construction of my invention applied thereto; Fig. 2 a central section of a flexible hose end with a somewhat modified construction of my improvement applied; Fig.

3 a side view of the. hose protecting cap shown in Fig. 2; and Fig. 4 a partly sectioned view of still another form of protecting cap.

Fig. 1 illustrates an ordinary flexible hose nipple 1 with a flexible hose section 2 clamped'thereon by means of the clamp 3. According to my improvement a cap 4 is provided which is preferablyfoi'med from brass tubing and having one end of rounded contour with the outer edge turned inwardly sufiiciently to prevent all possibility of the extreme end portion of the nipple coming'in cont-act with the inner tube of the flex ble hose. The rear portion of the cap may be made slightly taper so as to readily fit over the "end portion' of the nipple. With this formpf my invention, the cap is first placed over the end of the nipple and the flexible hose'is then slipped on and clamped in place in the usual manner. It. will now be seen that as the inner tube of the hose rubs on the rounded portion of the cap 4 in assembling, the hose is protected from damage by reason of exposure to the raw edges of the nipple end, and likewisein service the hose works about the smooth rounded portion of the cap and thus cannot be damaged.

In the construction shown in Fig. 2 the.

rotecting cap 5 is inserted within the flexible hose 6 at the proper distance from the end, preferably being placed on the mandrel in the inner tube in the process of vulcanizing, so, that when the hose is completed, the cap is firmly secured in place. The cap may be. provided with a number of longitudinal slits to allow for expansion when pressing the nipple in place, and the inner edge may be rounded in as desired to shield the hose from the end of thenipple.

The protecting cap 8, shown in Fig. 4, is

vented, and furthermore that the construction may be readily applied to the ordinary standard hose connections.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is 1. A device for protecting flexible hos'e,.

comprising a metallic cap adapted to fit over the end of a nipple, and a non-metallic cushion carried by the cap for engaging the In testimony whereof I have hereunto set flexible hose. my hand.

2. A device for protecting flexible hose ends, comprising a metal cap adapted to fit JOSEPH D. HARRIS.
